IMO our coaching staff takes the easy approach by switching as our primary defensive approach to screens and PNR. I would prefer if the staff focus on defenders fighting through ball screens. Better communication and help from teammates is crucial to execution of an elite half court defense. Developing a mental & physical toughness on the defensive side is the first priority. Even if a team effectively switches positions 1-4, a good opposing coach is going to create a matchup mismatch with the 5. Once guys become adept at fighting through screens, post hedging- then introduce automatically switching as another defensive technique.
